Milwaukee SE220 – Lab Grade Double Junction pH Probe for Milwaukee MW101 and MW102 PRO meters

The Milwaukee SE220 is a high-quality laboratory-grade pH electrode designed for precision measurements in demanding environments. It is fully compatible with Milwaukee MW101 and MW102 PRO meters, as well as any other pH meter equipped with a standard BNC connector.

The double junction design minimizes clogging and contamination of the reference junction, ensuring more stable and accurate readings even in complex or contaminated samples. The gel-filled system eliminates the need for refilling electrolyte, making maintenance simple and reducing downtime. The resin body provides excellent chemical resistance and mechanical durability, ideal for both laboratory and field applications.

The spherical glass tip ensures accurate measurements and quick response, while the durable 1-meter cable with BNC connector guarantees reliable connectivity.

Key Features:

Lab-grade double junction electrode for superior stability and accuracy
Gel-filled – no electrolyte refilling required
Resin body – durable and chemically resistant
Compatible with all BNC-type pH meters (e.g. MW101, MW102)
Spherical glass tip for precise readings
Designed for aqueous solutions, chemical preparations, and lab analysis

Applications and Maintenance:

The SE220 pH probe is ideal for measuring the pH of aqueous solutions, laboratory samples, and industrial or environmental applications. Its double junction structure provides superior resistance to clogging when used with solutions containing suspended solids or contaminants.

To ensure optimal performance and longevity:

Always store the probe in the recommended storage solution (never in pure or distilled water).
Clean the electrode regularly using a proper cleaning solution.
Calibrate after cleaning or long-term storage.
Gently stir the sample during measurement to speed up stabilization.
